摘要:
The polymer electrolyte membrane of the present invention includes polymers having a fluoroalkyl group and a proton conductive group. The present invention also provides a membrane-electrode assembly, a fuel cell system including the polymer electrolyte membrane, and a method of making the polymer electrolyte membrane by a chemical grafting method. The amount of the proton conductive groups in the polymer electrolyte membrane can be controlled, the membrane thickness can be easily controlled, adherence between a polymer electrolyte membrane and an electrode is improved due to the fluoroalkyl of the polymer, and long-term stability of a membrane-electrode assembly is improved.

A polymer represented by the following Formula 1, and a membrane-electrode assembly and a fuel cell system including the polymer: In the above Formula 1, definitions of the substituents are the same as in described in the detailed description.
摘要:
The present invention relates to a membrane-electrode assembly for a fuel cell and a fuel cell system comprising the same. The membrane-electrode assembly includes an anode and a cathode facing each other and a polymer electrolyte membrane positioned therebetween. The polymer electrolyte membrane adheres to the anode through a binder disposed between the polymer electrolyte membrane and the anode, and adheres to the cathode through a binder disposed between the polymer electrolyte membrane and the cathode. The binder and the polymer electrolyte membrane can include a cation exchange resin and an inorganic additive.

摘要:
A membrane-electrode assembly includes a polymer electrolyte membrane with an anode and a cathode on opposite sides. Each of the anode and the cathode includes an electrode substrate, and a catalyst layer is formed on at least one of the electrode substrates and includes at least one proton conductive crosslinked polymer. The membrane-electrode assembly may include catalyst layers that are positioned on opposite sides of a polymer electrolyte membrane, either of which includes at least one crosslinked proton conductive polymer.
